BACKGROUND OF THE INVENTION

As the rapid development of the heavy industry and the increasingpopulation result that the demand for the thermal power generation haveincreased. And both the emission of automobile exhaust and the amount ofout-door air-conditioner soar. All of these cause the climate warming.

In order to alleviate the discomfort caused by climate warming,air-conditioner and AC motor fan become the necessities of life.Recently many kinds of cooling garment products using different workingprinciple to reduce body surface temperature are appeared in market. Thegeneral pattern of the most popular cooling garment is zipper jacketwith opening and closing fore breast. The basic technology of thecooling garment is that in use all of the other part of the coolinggarment is close except cuffs and neckline. When the power is connected,two small-sized DC fan installed at the circular opening at the left andright ends of the waist in the cooling garment blows in the clothes. Theprinciple is that when the body surface is completely wet by sweat, thefan installed on the clothes transfers air lower than the body surfacetemperature from outside the clothes into it, and form circulatingairflow in the space between the body and the clothes. When the airflowglide along the body surface, it rapidly evaporates the sweat attachedto the body surface to produce heat of vaporization effect, thereforreducing the temperature of the body surface. At the same time, the heatin the blood that is contained in the capillaries of the body isexpelled from body as the sweat evaporates. This phenomenon istransmitted to the human brain through the epidermal nerve, so the humanbody feels cool. This series of physiological process constituteso-called physiological effect of human body air conditioning.

However, for the human body, water in the human body is, after all, avaluable and indispensable resource. When the amount of sweat secretedto a certain extent, in order to maintain that the function of otherorgans of the body will not cause dysfunction because of lack of water,or the body will not cause dehydration symptoms because of the largeloss of water, the body will slow down the speed of the secretion ofsweat, and less sweat is secreted from the sweat glands. What happens isthat very limited sweat is secreted and evaporates instantaneously. Sothe cool effect at initially using cooling garment will be more and morenot obvious. In addition, if the outside temperature of the coolinggarment is close to the body temperature, or higher than the bodytemperature, then use the cooling garment, input equal to or higher thanthe body temperature of air into the cooling garment, the effect will becounterproductive things.

This shows that the cooling garment can not be durable and effective tocool the human body in the hot conditions.
